Abstract

:

Heavy ion collisions at the Relativistic Heavy Ion Collided (RHIC, BNL) and
at the Large Hadron Collider (LHC, CERN) have revealed a new state of
matter, the so-called Quark-Gluon-Plasma (QGP). In this QCD plasma, the
quarks and gluons confined within the hadrons get deconfined over the
nuclear volume analogous to that in a QED plasma comprising of electrons
and photons. Precise estimation of the properties of this smallest and yet
the hottest droplet gives us a complete
understanding of how particles are produced via strong interaction.
In this talk, I will focus on one of the most important probes of QGP - the
collective flow of particles (hadrons) produced in a complex dynamics
that involves multiscale QCD processes. Standard methods and new approaches
to explore the collective flow of plasma will be presented. The
state-of-the-art models: Transport and Hydrodynamic, used to study the QGP
evolution will be reviewed. Finally, from the synergy between these
approaches, models and experimental data, I will discuss what we presently
know about the thermodynamic and transport properties of QGP and some
interesting open questions.
